The
CoLine™
Loudspeaker is a Coaxial/Coincident 2-way full-range Line Loudspeaker System
that solves coverage and reverberation problems in many applications. The
selection of drivers, physical arrangement, and most importantly crossover
configuration combine to make a multi-way loudspeaker system that behaves as a
single driver. There are no detectable notches in the system response anywhere
within the 160 degree horizontal coverage. The low and high frequency section
phase and
time domain behavior results in the low and high frequency driver outputs exactly
overlaid for perfect impulse response. As a result speech is easier to
understand and percussive musical sounds are reproduced with the same transient
signature as they are produced. Musical texture is much closer to an
un-amplified experience. All of the compromises that work to reduce the ideal performance
of a loudspeaker system have been addressed in this loudspeaker system. The Line
Array arrangement allows this loudspeaker system to provide high quality audio
in acoustically hostile environments such as large churches, convention centers,
large theaters and concert halls. In many cases delay zone loudspeakers far from
the stage are not required. Use of this loudspeaker system can eliminate the
need for acoustical treatment to reduce reverberation. This is a feature that is
usually desirable in churches and concert halls.

Even though this loudspeaker system is
compact it can generate 105db at 100 feet from the stage. And the horizontal
coverage is more than twice as wide as a popular ribbon driver at frequencies
above 2.5Khz. This means that more of the audience hears extended range audio.

Features, Benefits and
Uses

Even front to back
coverage of room. Listeners close to the CoLine™
Loudspeaker are not blasted while listeners far away hear at the same level
that conventional loudspeakers produce less than halfway back in the room or
better.

Dramatically reduced
susceptibility to feedback because of Line Array arrangement. Use of the
CoLine™
Loudspeaker allows much greater sensitivity and output with lavalier
microphones compared to conventional loudspeakers. This feature is very
desirable for theatrical performances.

Touring Theater: Excellent choice for
touring theater. Takes up very little downstage floor space and can be setup
and aimed in almost no time. No custom steel cages to aim multiple speakers.
No intelligibility reducing interference between multiple speakers
because only one is typically required on each side of the stage.

Cinema: No matter what loudspeaker
system that you use the reproduced by the loudspeaker system is compromised
because of the crossover. Above and below the vertical centerline of the
speaker system there is a notch in the frequency response of the loudspeaker.
For a typical 500Hz crossed-over system, this notch creates a hollow sound in
speech range. This is due to the to crossover used and arrival time
differences between the Low and Mid/High drivers. Three-way systems don't
solve this problem. In fact they create two places in the audio
spectrum where this notching of response occurs. Just because the manufacturer
doesn't show this in their data sheet doesn't mean that the problem doesn't
exist.
The shallow depth allows for compact placement behind the screen.

Scalability; as the floor height
front to back increases beyond the 76" height of the Coline model CL2-32 plus 5 degrees
above and below the front of the CoLine Loudspeaker, additional modules are added to assure that all
listeners ears fall between the bottom and the top of the CoLine Loudspeaker.

Local and Regional Sound
Companies are often called on to supply a support package for High School
and College Musical Theater. The Coline™ Loudspeaker is an excellent choice
because it is easy to deploy as down-stage speakers, provides excellent sound
even to the rear of a deep auditorium, and has less feedback
potential than conventional loudspeakers.
